Question

An expression of the type $\frac{28}{ab}$ does not form a monomial unless a or b is equal to 0. State if the statement is true or false.

• A. True
• B. False

Answer 1

The correct option is B

False

Since ab is a variable, it can take any value. If it takes the value zero i.e., if a = 0 or b = 0, the expression $\frac{28}{ab}$ will be equal to $\frac{28}{0}$ which is not defined. Thus, the statement is incorrect.
